Ours didn't do anything but make puffs of dust...........that's why the Chandler-spinner types are working the best for us.

I would think the same situation would happen when you start spreading the composted litter..........30% moisture ain't much.........

On the same token.........the Chandler rear spinner spreaders are ridiculous in the really wet stuff.........but we've been able to sidestep having to spread wet stuff most of the time.
